To resume: Music being a _physical agent_,--that is to say, acting on the individual without the aid of his intelligence; a _moral agent_,--that is to say, reviving his memory, exciting his imagination, developing his sentiment; and a _complex agent_,--that is to say, having a physiological action on the instinct, the organism, the forces, of man,--I deduce from this that it is one of the most powerful means for ennobling the mind, elevating the morals, and, above all, refining the manners. This truth is now so well recognized in Europe that we see choral societies--Orpheons and others--multiplying as by enchantment, under the powerful impulse given them by the state. I speak not simply of Germany, which is a singing nation, whose laborious, peaceful, intelligent people have in all time associated choral music as well with their labors as with their pleasures; but I may cite particularly France, which counts to-day more than eight hundred Orpheon societies, composed of workingmen. How many of these, who formerly dissipated their leisure time at drinking-houses, now find an ennobling recreation in these associations, where the spirit of union and fraternity is engendered and developed! And if we could get at the statistics of crime, who can doubt that they would show it had diminished in proportion to the increase of these societies? In fact, men are better, the heart is in some sort purified, when impregnated with the noble harmonies of a fine chorus; and it is difficult not to treat as a brother one whose voice has mingled with your own, and whose heart has been united to yours in a community of pure and joyful emotions. If Orpheon societies ever become established in America, be assured that bar-rooms, the plague of the country, will cease, with revolvers and bowie-knives, to be popular institutions. Music, when employed in the service of religion, has always been its most powerful auxiliary. The organ did more for Catholicism in the Middle Ages than all its preaching; and Palestrina and Marcello have reclaimed and still reclaim more infidels than all the doctors of the Church. We enter a house of worship. Still under the empire of the external world, we carry there our worldly thoughts and occupations; a thousand distractions deter us from religious reflection and meditation. The word of the preacher reaches the ear indeed, but only as a vague sound. The sense of what is said is arrested at the surface, without penetrating the heart. But let the grand voice of the organ be heard, and our whole being is moved; the physical world disappears, the eyes of the soul open; we bow the head, we bend the knee, and our thoughts, disengaged from matter, soar to the eternal regions of the Good, the Beautiful, and the True.
